l Specification forming part of Letters Patent No. 198,091, datedDecember 11, 1877 application filed october 24, 1871. l

-upper ends of the legs passing through same.

Fig. 4 is an enlarged side elevation of the swinging bar and its parts.showing the knife-ed ge of the swinging bar engaging theshoulder-bearing of the casting. Fig. 6 is a longitudinal sectionthrough the seat.

The supporting-frame consists of the legs A and the canopy A', fromwhich the swinging parts are suspended. The legs A are secured at top inthe canopy as follows: I ,cast a casting, B, of the constructive shapeshown in Figs. 2, 3, said casting having the longitudinal sides b b, andthe sloping transverse sides b1 b, terminating with the shouldersbzV b2.In the body of the casting B are made two mortises, b3 b3, the oppositetransverse faces of which slant or incline. lines in Fig. 2, also shownin Fig. 3.) It is through the mortises b3 b3 that the upper end of eachleg passes to be united to the casting and canopy, the inclination ofthe faces b3 b3 being to suit the inclination of the` legs when spreadtransversely to the position of the canopy. The side b of the casting ismade slanting, to enable the legs to be secured thereto so that the legscan vhave their lower ends s'pread somewhat apart in a directionlongitudinal to the position of the canopy, and thus make a stillfurther support for the swing proper.

Forming part of the casting B is a lug projection, C, having theshoulder-bearing at c. (See Figs. l, 2, 3,- and 5.) Two of the castingsB are constructed for each swing, each casting fitting in acorresponding mortise made near each end of the canopy, (see Figs. 1, 2,and 3,) and secured to same by bolts passing through the shoulders b2b2, firmly fastened Fig. 5 is a detail,

(See dottedl with nuts. The upper ends of the legs pass through therespective m'ortises b3, and are secured in any proper manner.

D is the swinging bar of metal, cast with upright pins d d, the ends ofsaid bar at d* dl being knife-edges, (seeFigs. l and 4,) the knifeedgesbeing t0 engage the shoulder-bearings c, and a counter-weight engagingthe pins d d. Near each end of the swinging bar D is bolted the upperend of the hangers E, the lower end of each thereof being bolted-to thecorners of the seat. (See Fig. l.)

E is avertical arm. Its upper end is bolted to the swinging bar D,thelower end of the arm. being carried down, as indicated in Fig. 1, incenter of the seat.

F is the seat. This can be of ordinary pattern and construction, but Iprefer to make a seat havingthefollowing constructive features My objectis to becapalole of converting the seat into a cradle. Hence I constructthe seats f proper to have hinged thereto one or more wings,f. (SeeFigs. 1, 6.) Both the opposite wings j" can be raised and secured in ahorizontal position, thus forming afalse bottom, which changes the seatF into a cradle. (See Fig. 6.) When not used as a cradle the hingedwings are placed vertical, or folded out of the way, and the seats fproperly used as such. See full lines in Fig. 6.)

In order to swing or oscillate the seat F (or cradle) so suspended fromthe bar D, the following arrangement of parts is provided: There are twoslots, d2 d2, in the canopy, through which the pins d d of the harpasses, and Vwith sufficient clearance for said pins to oscillate.

-Gr is a counter-weight, having the hollow stems g, which engage thepins cl d, (see Fig. 1,) said weight being to counterbalance and easethe oscillation of the swinging parts.

H is aprojecting arm, secured to the canopy so as to incline to the rearthereof, (see Fig. 1,) and in the lower end of said arm a roller isprovided.l Top of the canopy is secured a bracket containing a groovedroller, i'. The

arm h and roller i are arranged in line with the center rarm E. (SeeFig. 1.)

J is the cord. One end thereof is secured to the arm E thence said cordis carried over the roller in the arm H, from thence over y ator.

ing parts. The swinging action is, by this construction and arrangement.of parts, facilitated by the fact that the cord is passed from thecenter point over the rear projecting arm H, and carried forward overthe top roller i. Specially be it noted that the knife-edge bearing ofthe swinging parts reduces the friction to the least, and added to whichis thecounterbalance to produce a swing easy for operation.

When the cradle is used, the cord J, instead of passing through thecanopy, can be 'carried over the front of same, and made to extend toanyrdistance, so that the operator can swing the cradle seated away fromsame.

The seat or cradle can be disengaged from the hangers, and in its placea hobby-horse,

&c., can be secured.

WhatIclaim is- I 1. In a swing, the bracket B, having 'the mortises b3b3, the lug-projection C with'the But a slight vertical reciprocation ofthe cord J oscillates the swingshoulder-bearing c, as and for thepurpose set forth.

2. The swinging bar D, having knife edges 4d1 dl, in combination withthe shoulder-bearings c, as and for the purpose set forth.

3. The counter-weight Gr, having hollow stems g, in combination with thepins d d, as and for the purpose set forth.

4. The combination of the hinged sectional wings f with the seats f, asand for the purpose set forth.

5. The combination of the cord LI, roller i', arms H E', bar D, havingknife-edges dl, the bearings c, hangers E, seat F, the canopy A', legsA, all said parts being constructed to operate in the manner and for thepurpose set forth.

6. The combination, with the part-s mentioned in the preceding claim, ofthe pins d d,

and counter-balance G, to operate as set forth. In testimony of saidinvention I have here# unto set my hand. Y JOHN F. ELLER. Witnesses:
